In industries where temperature extremes, vibration, or hazardous process environments are part of daily operations, accurate and reliable temperature measurement becomes a serious challenge. In these environments, operators need instruments that deliver accurate readings from a safe distance, reducing the need to approach hazardous areas. Gas-actuated thermometers are an effective solution for these applications. Their robust design, wide measurement range, large dial size and remote mounting capabilities make them ideal when both safety and accuracy are priorities. As a global authority in pressure and temperature instrumentation, Ashcroft has helped manufacturers and process operators improve reliability and reduce downtime for more than a century. In this article, you’ll learn: How gas-actuated thermometers work When and where they are most effective Why remote mounting and thermowell selection matter Which design options can extend instrument life in extreme conditions
